The gasketed plate heat exchangers of the AV and AX series can be built with material suitable for contact with food. The pack of plates for the heat exchange is held together by two containment plates and the necessary linkage, both in AISI304 / 316 stainless steel. The plates constitute two channels, one for the hot fluid that transfers heat to the other, and one for the cold one that receives the heat. The sealing of the channels is ensured by gaskets suitable for food contact, in different materials depending on the operating fluids. The inspectable exchanger has the main advantage of flexibility, since it can be built following all the customer’s requests and needs. It can also be disassembled into its individual components. This guarantees more efficiency in cleaning and maintenance operations, as well as making the thermal processes to which it is subjected flexible with the possibility of expanding the exchange surface by simply adding plates inside the pack.
